I had my baby in April 2009 and after my six weeks I was already back down to my desired weight a week later I got the mirena and started to gain it all back I asked the doctor at my 3mth follow up and he said weight gain was not a side effect. Also I beleive that I am losing alot of hair from this medication. About 3 weeks ago I was cramping really bad and I never have had cramps then I went to bed the next day I woke up and could not move I felt as if I had the most severe flu like symptoms ever. I had 104 temp chills low blood pressure. I was freezing cold but sweating like no other. I tried to stick it out took some aleve and theraflu they did not help. I was shaking like I was in a freezer but my body was burning up. My head felt like it was going to explode. I was vomiting but I could not eat so I had nothing to throw up. So the next morning I woke up after not really getting any sleep I felt misriable I had my boyfriend take me to the emergency room I felt so bad I could not even get myself dressed my boyfriend had to even put my shoes and socks on. At the emergency room they took my vitals my blood pressue was 54/92 and even got lower than that. My pulse was 140 my temp was 103.9 ..basically they said if I had not come in I would be dead. They took some urine and blood and there was an infection in my urine so they started me on antibiotics then they told me something was abnormal in my liver, I do not drink but maybe once a month if that usually just on occasions so I did not understand what was wrong with my liver they said I had to be admitted for 2 days to do some blood tests and keep an eye on my liver issues. After 30 tubes of blood they said I had bateria in my blood which most likely inflammed my liver, they think the bacteria was from a uti I had developed.All the tests came back negative for the liver problems it was just inflammed
